Crash in RedistributeDataForOrderedCompositing when transparency is used.

archive: bugOrderCompos.tgz

Description

I have a crash using pvbatch. Trying to save a screenshot of a contour computed on a data set, shown with transparency, the execution exit with:

terminate called after throwing an instance of 'std::runtime_error'
  what():  -1 2.77602 2.79778

Loguru caught a signal: SIGABRT

The stacktrace include the following lines:

29      0x154b839ebb0e vtkPVRenderView::Render(bool, bool) + 1666

Here is the full version

From GDB, the last interesting context is on the following line: paraview/VTK/ThirdParty/diy2/vtkdiy2/include/vtkdiy2/detail/algorithms/kdtree.hpp

 380                 if (loc < 0)     
>381                     throw std::runtime_error(fmt::format("{} {} {}", loc, x, link->core().min[dim]));

Step to reproduce

1. Extract the archive given in the first line of this issue
2. Execute: mpirun -np 2 pvbatch kitwareScriptContour.py

The bug occurs only in specific conditions:

• The script is executed using pvbatch
• MPI is set up to use 2 cores (also bug with 5)
• Transparency is used (see the content of kitwareScriptContour.py)

System

• Linux
• Gcc 10.1.0
• ParaView master

@utkarsh.ayachit can you help me with this one ?
